用微界面电解池和四[3，5-双（三氟甲基）苯基]硼酸双（三苯基膦基）铵（BTPPA（+）TFPB-）首次记录了水（W）-甲苯界面上的离子转移伏安图。室温下BTPPA（+）TFPB（-）在甲苯中的高溶解度使得能够进行电化学测量。当以10 mmol dm（-3）NaCl为支持电解质时，在W/甲苯界面的电位窗口约为1.09 V，比在W/1，2-二氯乙烷界面的电位窗口大0.30 V。发现季铵离子穿过甲苯界面的转移反应是可逆的。对W垂直棒向甲苯的离子迁移形式电位进行了评价，并在W硝基苯、W垂直棒1，2-二氯乙烷和W垂直棒2-硝基苯辛基醚界面上观察到这些形式电位与标准电位之间的线性相关性.
Voltammograms of ion transfer at the water (W)vertical bar toluene interface were recorded for the first time by using a micro-interface electrolytic cell and bis(triphenylphosphoranylidene) ammonium tetrakis[3,5-bis(trifluoromethyl) phenyl] borate (BTPPA(+) TFPB-). The high solubility of BTPPA(+)TFPB(-) in toluene at room temperature enabled the electrochemical measurements. The potential window at the Wjtoluene interface is about 1.09 V, which is 0.30 V larger than that at the W vertical bar 1,2-dichloroethane interface when using 10 mmol dm(-3) NaCl as the supporting electrolyte in W. The transfer reactions of quaternary ammonium ions across the Wjtoluene interface were found to be reversible. Formal potentials for ion transfer from W vertical bar to toluene were evaluated, and linear correlations were observed between these formal potentials and the standard potentials reported at the Wjnitrobenzene, W vertical bar 1,2-dichloroethane, and W vertical bar 2-nitrophenyl octyl ether interfaces.
